If you're using OSX, then it's wise to have a decent burner app. ie: Roxio Toast. Toast 6 in particular has had xtra movie functions added such as for CD/DVD menus & conversion. I won't stop your fun for searching & finding the best video formats to dwnld for mac. However if you have Toast & read the manual it will tell you anyway (basically almost anything that can be recognised by QT.) That's enough hints. lol
